lymph nodes

Small oval or bean-shaped bodies, up to 2 cm in length, situated in groups along the course of the LYMPH drainage vessels. The nodes have fibrous capsules and are packed with lymphocytes. The main groups of lymph nodes are in the groins, the armpits, the neck, around the main blood vessels in the abdomen, in the MESENTERY and in the central partition of the chest (the MEDIASTINUM). Lymph nodes offer defence against the spread of infection by producing ANTIBODIES, and become involved in the spread of cancer. They can become cancerous, forming LYMPHOMAS.

Lymph nodes
